Esteban is from a Spanish hydraulic equipment manufacturing company. Some time ago, their company customized a hydraulic cylinder for a customer. The hydraulic check valve, relief valve and electromagnetic unloading valve in the system are all standard parts from HydraForce. The customer is basically satisfied, but the cylinder structure is not very satisfactory, and the price has no advantage. Their engineer said that only by integrating the functions of hydraulic check valve, relief valve and electromagnetic unloading valve, and replacing them with only one hydraulic screw-in threaded cartridge valve, would the structure be simple and the cost be reduced. Esteban inquired about more than 10 hydraulic threaded cartridge valve manufacturers, but no result for a week. Esteban was worried.
After browsing AAK website on Google, Esteban found that AAK had many cases of solving customer problems, and sent an email asking: Can AAK customize the multi-function hydraulic threaded cartridge valve to make the cylinder compact and reduce costs? After communication, it was learned that Esteban needed AAK to customize the hydraulic threaded cartridge valve to replace the functions of the 3 valves in the system. According to the hydraulic schematic diagram provided by Esteban, AAK engineers basically had the idea. Esteban asked for samples after knowing it. After 50 days, AAK sent 10 samples of hydraulic threaded cartridge valves. 1 month later, Esteban informed us by email that the customer was satisfied with the new structure of the oil cylinder, and should promote it first, and let us wait for the batch order.
AAK used an integrated multi-function hydraulic threaded cartridge valve to replace the 3 valves of the original system, specifically as follows:
1. The valve housing is provided with a connecting valve hole, a working port of the oil cylinder, and a hydraulic control port, an oil inlet port and an oil return port. A check valve spool is set in the valve hole to control the on-off of the oil inlet and the working port for oil feeding or unloading. In this way, the one-way control function is realized and the check valve of the original structure is replaced.
2. The control check valve spool is separated from the working port, and the hydraulic control valve spool for unloading the oil inlet and the working port is connected. At the same time, the connection between the valve hole and the relief valve spool of the oil return port can also be disconnected. In this way, the overflow function is realized and the relief valve of the original structure is replaced.
3. The relief valve spool is equipped with connecting valve hole, oil return port and damping hole. One end of the damping hole is equipped with a unloading valve spool to control the opening and closing of the damping hole and the oil return port, and the check valve spool is equipped with a connecting channel to connect the valve hole and the working port for overflow or unloading. In this way, the unloading function is realized and the electromagnetic unloading valve of the original structure is replaced.
AAK hydraulic threaded cartridge valve, can not only replace 3 valves of HydraForce with 1, but also realizing multi-function and flexible adjustment.
